FUEL-SUPPLY TANK.

Specication of Letters Patent.

Patented June 24, 1913.

To all whom it may concern Be it known that I, FREDERICK G. FARR, a citizen of the United States, and resident of Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Fuel-Supply Tanks, of which the following is a specification.

This invention relates to improvements in oil storage and distribution systems for boats.

The objects which the present invention has in view are: to provide a system for feeding oil from a storage tank under a constantly equal head: to provide a system wherein the pressure for feeding oil to the engine is automatically controlled: to provide means for automatically receiving oil into t-he storage tank while maintaining the oil feed pressure: to provide a storage tank for liquids wherein there is provision made for avoiding the surging of the liquids.

One embodiment of the present invention is shown in the accompanying drawing, which is a diagrammatic view of the invention, showing the same as installed in a boat.

The View shows a forward section of the interior of the boat.

The invention is particularly designed for the equipment of motor boats wherein gasolene is carried. The storage tank for the gasolene is usually placed in the bow of the boat while the engine is preferably disposed in the stern, or midships of the boat. The engine is connected to the tank by the pipes 3 1- the former being the gasolene feed for the carbureter while the pipe -4- is for the delivery of water to the storage tank, this water being pumped by the engine either as a part of the water circulating system of the engine or as an adjunct thereto. If the pump is a part of the circulatory system of the engine, suitable provision must be made for cooling the water before introduction into the tank 5.

The gasolene -6- in this invention is contained in the tank n-5- and is supported therein by the water -7- which is introduced below the gasolene, preferably into an extension or leg -S. It will be understood that the gasolene contained in the tank -5- is delivered therefrom by water being introduced into the tank and displacing upward the said gasolene.

vthe side of the boat.

The relation between gasolene and water in their specific gravity is that of 17 to l2. In other words, a column of water l2 inches high will support a column of gasolene 17 inches high. In the present invention this `fact is utilized in that we have provided' a constant waterhead which is in the present situation the top of the chamber -9- into which the supply pipe -4- delivers the water and from which is extended an overflow pipe l0-- that leads to the outside and discharges the surplus water beyond The chamber -9- is provided with a pipe -11- which extends in to the bottom of the leg -8- of the tank -5- and constituting the water-inlet therefor. In the introduction of water, it is carried through the pipe *4L- into the chamber -9- and from thence into the bot-tom of the leg 8- and then it is carried upward through the said leg to spread over the bottomfof the tank -5- to support the gasolene -6- contained therein.

The column of water extending from the bot-tom of the tank -5- to the top of the chamber -9- will support a column of gasolene of the same height plus fivetwelfths of the water column. The same column of water will of course support a column of water of the same height. Therefore a column of water and gasolene mixed will be supported by the same water column to a height in excess of the column of water, proportional to the mixture. In other words, the head of the water column will be constant, while the head of the gasolene column will be constantly lessening as the proportion of gasolene in that column diminishes. Within this range of diminut-ion of the head of the gasolene columns there is introduced a sight gage -12 The enlarged pipe section 13- which is extended from the top of the tank 5- is in open communication therewith. From the section -13- is extended a smaller filling pipe 14.- provided at the upper end with a funnel -15. From the pipe --ll and just above the top of the section 1S- is extended the oil delivery pipe -3- which leads to the carbureter for the engine. The gage 12 is preferably connected to the pipe 14 at a point above the pipe 3. By this arrangement when the gage indicates that the gasolene has been exhausted there will. still be a supply in the tank which tends to prevent the tank from being drained of gasolene.

rthe section 18 serves as a separating chamber to permit any water which may be held in suspension in the gasolene to settle and separate from the gasolene before entering the pipe 14. The pipe lt being ofV small diameter as compared with the section 13- it operates to retard the npward movementof the gaselene contained in the section 12%. rllhis retardation permits the water to separate out. lt is to prevent any agitation of the gasolene contained in the section 1:3 which might arise from surging of the gasolene centained in the tank 5 that l have provided the flared extension 1G which is shaped somewhat after the form of an inverted fruste conical section. 1n operation should the material in the tank -5 surge, this extension would deflect. the material downward from the opening of section 13. li'lounted within the inverted frusto conical men'iber 1G is a deilector 17, preferably cone shaped, which is supported from the member 1G by arms 18. The purpose here is that during the operation of filling, the gasolene is caused to spread and is pre* vented from boring.

T he operation of a device of the character described is as follows: The supply to the carburetor being closed, gasolene is poured into the funnel 15. As described, the column of water of a height to the overflow 10 will sustain a column of gasolene only, to the top of the gage 12. Therefore as the gasolene now poured into the funnel 15 and pipe M the column of gasolenc and water represented by the tank section 13 and pipe 11i-- becomes heavier than the column of water contained in the pipe 11 and there fore the water contained therein is forced out of the over-flow 10. This continues as the gasolene is poured in, until the tank 5 section 13 and pipe lt becomes filled entirely with gasolene when it will be found that the balance between the gasolene column and the water column has been reached and the gage 12- will show the head of the gasolene at the top of the said gage. ills the engine is operated, the gasolene is consumed, but the hydrostatic pressure on the gasolene is sufficient to maintain the level of 'the gasolene within the pipe lll above the point of communication of the pipe 3 therewith until the tank is practically emptied of gasolene. The water circulation vsystem is continuously operated by the engine to deliver water .into the chamber 9. lf the said chamber is iilled, the surplus is delivered from the overflow 10 beyond the outside of the beat. lit the chamber Q has become in any way exhausted by the decline of the water contained therein, due to the lessening ofthe balancing gasolene column, then the water circulation immediately replaces the exhaust to maintain the water column constant. This operation is automatic and continuous. The water is constantly displacing and replacing the gasolene, as the same is being consumed. ils the gasolene is consumed, however, it will be noticed that the gasolene column is becoming` gradually more largely rater and the combined water and gasolene collnnn is more nearly ap* preaching the vater cohunn. rllhis result-s in a gradual diminishing index on the gage 12.

That l claim as my invention is:

1. ilhe combination with a tank, of a water inlet connection for the tank communicating therewth adjacent its bottom, a separating chamber located on the top of the tank and provided with an inverted frusto conical. wall at the lower end of said chamber, and an oildelivery pipe communicating -with said separating chamber.
